They do not become free radical themselves when they give an electron to the unstable molecule, because they have the special capacity to remain stable with or without the electron. It is through this interaction with the free radicals that the vitamins are able to assist in the prevention of damage to tissues and cells that could lead to disease.
Numerous studies have found that they may offer protection against a variety of cancers. Other studies have associated them with helping to lower blood pressure. Controlling free radicals is thought to be an important part of defending the body and the mind against the effects of aging. In addition to continuous studies concerning the potential in preventing cancers, heart disease, and diabetes related conditions, researchers are also paying close attention to the possibilities antioxidant vitamins may hold for Alzheimer's disease.
The free radical lacks an electron because it is the result of the splitting of a structure weakened by either one of the body's natural metabolizing processes or by some external contaminant, such as pollution or cigarette smoke. The free radical attacks other molecules, seeking its missing part, which leads to its molecule victim becoming a free radical as well. When enough free radicals accumulate with a cell, the cell can be damaged, or worse.
Antioxidant vitamins have the power to bring these free radicals under control. They do this by meeting the free radicals' most basic needs, by giving them the electrons they need to be stable. Thus, the they remove the free radicals' motive for aggression and crime -- their motive to attack other molecules to steal their electrons, thereby creating still more free radicals -- and bring an end to the free radical crime wave that threatened the very existence of their world and restore social order and peace to their world, the cell, and perhaps even to their universe, the body.
